T0 afl whom 'it muy foncer?? e Be it known that we, 'lrnionnus F. BA1LY and. Fiumi T: Corn, citizens of the United States, both. residing at Alliance, in the county of Sterk and State of Ohio, have 1nvented n new and useful Sheet-Feeding Ma Chine, of whioli the following n specificetion..

This invention relates to sheet feeding ma,- chines und luis more Jecial reference to n. deviee adopted to feed, sheets from apar or tank preporfuory to plowing the sheets in :L tinnng pot. n l V The object of the present invention 1s to provide u device udupted to automatically feed sheets singly from e. nur or tank'.

A further ohjecl'. ie the provision of a. fle- 'vice o? this (1l-latenter which will feed the sheets upon t. suitable table, from. which they may be manually removed und to so oonstrl. et the devine that should the operatorleuve the .uumliine- :for n few minutes the ma t chine will be :u ztoruutioally stopped after u certain number of sheets have been fed therefrom. i,

A still further object to provide u device of this chere-eter which is suspended above the our or tenir und automatically moves along the len "th, thereof as the pack of sheets therein dgirninished.

l With these objects in view the invenF tion consists the novel construction and arrangement of parts, hereinafter described, illustruted in the accompanying drawings, und particularly pointedout in the appended elzlnn,4 it being understood that "verlous changes in the form, propor- "tions, size and minor details of Iconstruction mybe made within the scope of the appended claim, without departing from the `spirit or sacrificing any of the advantages of the invention.

Fig. 2 is 'a side elevation of the seme.

Fig. 3 is n. front elevation of the seme.

Fig. 4 is e side elevation of one of the side frames. Fig. 5 is a detail sectional view of the three-Wa Y valve which controls the operation ofl t e suction cup.

F ig. (5 is a. detail view shown'g a modified form of the device. i

Similar numerals of reference indicate corresponding arts throughout the several figures of the rewings.

Referring more especially to the construction illustrated Vin the aceompanyin drawings, the numerals 1-1 indicate trac portedin any suitable 4manner and adopted to carry the sheet feeding mechanism, the curs, such as indie-ated by the numeral 2, being adapted to run beneath seid tracks as shown in Fig. l. The numerals 3*?) indicate side frames upon which the feeding mecha nism is carried, the wheels 4 being rovded in said side frames by'means of wiich the device may be moved upon the tracks `1. Rolls 5 and` 6 are journaled in suitable bearings 7 and 8 respeetivel which are' carried by the side frames 3, t e bearings. 7 being 'slidably mounted within slots 9 formedin the side frames, springs 10 being located-between said bearings 7 and stationary blocks 11 forA the purpose of holding the 4rolls 5 and 6 together. A gear 12 is mounted u on the shaft 13 of the roll 5 and 'meshes wit a, gear 14 mounted 4upon the shaft 15 of the suproll 6, the ear 12 also meshing with an idler 1,6, said i ler meshing with n'pinionb' 17 mounted upon a. shaft 18 of the motor '19.

The motor 19 is preferably mounted upon, .a bracket 20 suspended between 4the side frames as best illustrated in Fig. 3.

A large gear 21 is mounted upon each of the side frames and meshes with a small gear 22 mounted upon the shortshaft ',513 and uponea-ch of said gears is vmount-,edit roller 23, the pvoted arms '24 resting upon' said roller, each of.said arms being pivotally mounted at 25 to one of the side frames. The forward extremities of the arms 24' lare connected by4 means of a rod 26. Apair-o'f downwardly depending arms 27 are carried by the rod 26 and at the lower extremity of eareh of said `arms 27' is ivotally connected a suction cup 28, a, 4flexi= le hose l29 laidng 'to a.. threel from each of'said suction cups wey valve 30.

he valve 30 is preferably swung from';a flexible' hose 31, which leads to' a. suction pump or" some equvalent'devce and 'an `eir inlet 32 is provided within said valve for the tot,"

purpose hereinafter described. The rota- `table plug 33, within the valve casing is pro-` Vim ' of the arms 27 is provided with a bracket f of the able 'for uw 40 and between said `brackets and the bracket 41v provided upon the rod 26v is inter osed y,

a coil'spring 42 for 'the purpose of ho ding the suction cu in en agementwith the outer faceV of the ,orwar sheet inthe car, the sheets being designated by the letter A. The suction cups are pivotally mounted upon the arms 27 Vin ordenl to adjust themselves to the an le of the sheets. a

I deflector plate 43 is pivotally mounted between the side frames and beneath the rolls 5 and 6 and adapted to guide the u per extremity of the sheet between the ro ers. Mounted upon said deflector vplate is a pair Vofv arms 44, ,the lower extremity of which are provided with'anti-friction rollers 45 adapted to contact with the face of the outer sheet. .A pivoted button 46, or some otherv suitable locking means, is provided to nor'- mally hold the -defle'ctor plate and arms' against movement, vsaidplate being` pivoted in order. to" allow the arms tobe raised sufi ficiently t clear the top of a car when a .new

car is moved into position beneath the feeding device,

An inclined table 47 -is pivotally mounted btween the side frames and beyond the rolls 5 and 6 and-adapted to r'eeeivethe sheets as they are passed through the rollers. The lower extremity of the table is supported upon 'a plate 48 which is slidably mounted upon the tracks 1,'a s ring 49 boing interposed 'between the tab e and said plate. A

ltop 50 is .provided near the lower extremity purpose of engaging the lower extremities o the sheets as they are piled upon the table. The late 48 is providedfwith' a bracket 51-. w ich carries `'an electrical contact 52 adapted to contactfwith a contact 53 carried upon the table ,47. The wire 54 which leads from the source of electrical 'supply is :connected with the contact 52 and a wire 55 leads fromthe contact 58 to the motor 19. 4The other wire'56 returns.

from the supply line to the motor, thus it 'will-.be seen jthat when the table is in the positionshown in Fig. 1 of the drawingsthe circuit from the source of 'supplyfrom the motor is closed-and the motor wil-lbe operated.' Should the o' rator of the device leave the niaeh'* e for a ew moments it would not desire le to have the device continuing and passes over a ulley 58, a weight 59 beingr connected to t e extremity thereof.

. he curs 2 which contain the sheets A are filled with water above the/level of the `sheets as shown in Fig. 1. These cars are run beneath the tracks 1-1 upon which. the feeding device is carried. The yoke 37 should be tilted Abaekwardly allowing the pivoted arms 24 to be raised, thus raising the rms 27 and the suction mechanism above the level of the Aear or tank when euch new om' is placed in positioii or an emptied cai. is moved from. beneath the feeder, the arms 24 hein pivcted at 25 to allow this movement. be turned to allow the arms to he raised Aforwardly to clear the top edge of the car as eueiinew car is brought beneath theA device und then the arms ay be lowered 'iito'f the position shown in ig. l and the latch #t T e latch 46 should gg 44 will bear against the surface of thfr. ward sheet preventing: an f11i-the-rmgvef= ment of the device towart the rear-fof thef: car, the weigl1t59 heldingtlie device in. this position upon the tracks. Vihen the -v device is operated as the arms 24 move'A downwardly they" will contact with the..4 fingersA 39 turnin position shown in vig. fcreating a suction. within the suction 28 and as tliem'ms.. are raised in the'positicn shown invFigLl the outermostsheet of the peck willf'l'j'e raised by said'suction cups, the' upper edge of said sheet engaging the dcflector late 4355 und being thrown between the rolls whichgrasp the sheet and carry. the surte#l upwardly depositing the sheetupon the table 47 from whence the sheet ma 'be movednby` the operator-and pla l t-innirip' pot or other device. As'` the 24 reach the upper limit of their move-` ment they contact with the fingers 88 turns?? ing the valve 30 suiiicientl to'conneotith air inlet 32 with the hose ine 29 bynie ao of the port 35,` thus allowing'alr' to dow v into the suction cups and releasing the sheetVI from said suction cups as the sheet 1s grasped' by the rolls 6 and 6;- The suction cp will thus be released from the sheets unls the arms 24 reach their lowermostylimitA ,when they will contuet'with the fingers 39 the vvalve 30 into the? ics 4 device to travel so that t carry 'it Lia-repos always above the outermost sheet ofthe pack.4 W f In Fi 6 is shown a slightly modified formo construction in which electromagnets are used ,to feed the sheets to the feed rolls instead of the suction cups above'4 described. An electro-magnet 60 is pivot- -ally mounted upon the lower extremity of each of the arms 27 and two Wires lead to said magnet, the wire '6l leading from a source of electricalsupply and the Wire 62 leading from the magnet to the contact 63. A Contact 64 is provided upon 'the arm GG and adapted to engage the contact 63 as the arm 36 1s o erated in the -usual manner, a wire 65 -lea ing `from the Contact 611 to the source of vthe electrical supply. By this construction the circuit to t e magnet is closed as the arms 24 descend, energizin the magnets and causing them to take hol of the outermost sheet of the pack and as the arms 24 are raised into the position.

shown in Figli they will'conta-ct with the 'fingers 38 breaking the circuits to. the magnets thus denergizing the .magnets .thus' `allowing the sheets to be fed to the feed rolls.

The same result as above described might also be obtained by providing an endless conveyer table above Vthe tank adapted to e feed rollers are .ence su gests, without departin carry the sheets from the tank to the operster, `an adhesive lifting device bein provided to lift the sheets from the tan and delivering the same to sind conveyor.-

Al-though the drawings and above s ecivfication disclose the best mode in whicl we have contemplated embodying our invention we desi'reto be not limited to the details of such disclosure, for, in the further practical application of our invention, many changes in formV and constructionmay be made, as circumstances reqnireor experifrom the s irit o the invention, within t e scope of t e appended claim.

We claim 1 Ina device of the character described, the combination with a tank containing a pack of vertically 'disposed sheets of a horizontal track located above said tank, a frame mounted for movement upon said track, an arm carried by said track and extending into the tank,` a roller provided upon said arm and arran d to oontactwitii the outcrmost sheet of t e pack, a pair of feed rollers carried 1n said frame, means for moving Y said frameto .hold said feed rollers above the outermost sheet of the pack at all times, an. oscillating arm piv-oted upon saidfraine,

means for ,oscillating said arm, a' vertically reciprocating arinpivotally connected to said oscillated arm and adapted to extends'- into' said tank means upon said `reciprocating arm for adhesively engaging the-face of the outermost sheet of the.l pack and means for releasing said sheet after the reciprocating arm reaches the 'upward limit of'its movement.
